FISCHER, OF BROOKLYN, NEW YORK, ASSIGNOR TO EUGENE,LTD., OF NEW YORK, N. Y., A CORPORATION OF NEW YORK CLIP AND SGALPPROTECTOR Application filed January 4, 1929. Serial No. 330,242.

The invention relates to a known type of device used in hair waving,which is clipped about the inner end of the cover of a pad surroundingthe curled lock of hair, for the purpose of sealing the end of the padnext the scalp to avoid the escape of steam on the scalp. Such knowndevices consist each of a pair of curved plates hinged together at onepair of extremities, and provided at the other pair of extremities withautomatic snap-engaging elements cooperative at a series of positions,when these extremities are pressed inward so as to pass one over theother, in order to hold the clip clamped about the cover and the lock ofhair;

The plates of these devices often become bent so that the snapengagement fails to hold. The resilience of the metal of the plates,plus some possible looseness in the hinge, being relied upon to afiordthe give necessary for the snap action, the holding soon becomesinsecure, even though in the beginning the operation may becomparatively stilt". The opening of the clips, after the heat treatmenthas been completed, is also inconvenient, and often causes discomfort tothe patron.

The object of this invention is to make a device of this character whichis more durable, in which the holding is rendered more secure, and inwhich the operation of opening the clip is facilitated. The manner inwhich these ends are attained can best be explained in connection with adescription of the preferred embodiment illustrated in the accentpanying drawings, wherein:

Fig. l is a sectional View illustrating the application of the device toa lock of hair and to a pad;

Fig. 2 is a plan View of the device;

Fig. 3 is a side elevation of the same;

Fig. i is a front elevation; and

Fig. 5 is a section taken on the irregular line 55 of Fig. 2.

The device comprises a pair of generally flat, thin, curved shieldplates 2, 3, the curved inner edges 4 of which enclose an opening 5 ofvariable size when the plates are moved in ward one over the other.

One pair of extremities are superposed and are connected, in part, by astud 6, which is passed through holes pierced in these extremities. Thestud is preferably riveted to the extremity of one plate, in thisinstance the plate marked 2. It projects above the extremity of theother plate, and is provided at a distance from this plate with a head7. Between this head and the face of the plate 3 a stilt compressionspring 8 is confined, the action of this spring being perpendicular tothe plates so as to hold the superposed hinged extremities firmlytogether, but with some capacity for slight yielding in the spring.

One of the plates is formed in its other extremity with a low struck-outlatching projection 9 having its forward side formed on a slope and itsrear or holding side comparatively abrupt. The cooperating extremity ofthe plate 3 has a series of openings or recesses 10 into which theprojection 9 on the face of the plate 2 will snap successively whenthese extremities are moved over each other-in the closing direction,thereby locking the clip against opening out and causing it to beclamped against the back or cover of a pad surrounding the lock of hair.Fig. 1 shows it so applied, (a being the lock of hair, 0 the curler onwhich the lock of hair is wound, d being the moistened pad, and Z) theimpervious or non-porous back or cover of the pad.

One of the plates is offset or bent intermediate its ends, as shown at11, so that its extremities lie in different planes, causing oneextremity to underlie and the other extremity to overlie the otherplate. This reversal of superposition between the hinged extremities andthe snap-locking extremities materially improves the locking action andrenders the clips stronger and more durable. It is of particularadvantage in connection with the spring tensioned hinge.

In the particular embodiment shown, it will be observed that the hingedextremity of the plate 2 underlies the hinged extremity of the plate 3,whereas the free extremity of the plate 2 overlies the free extremity ofthe plate 3 when the clip is closed. One of the effects of this is tocause the hinged extremities of the plate to fulcrum against each otherand to draw the head of the stud 6 against the spring 8, increasing thecompression of the latter.

The locking elements 9, 10 coact between overlapping portions of theplates in such manner that as these portions slide over each other fromo'ne locking position to another the faces are forced apart in adirection perpendicular to the plates against resilient re:

sistance which; presses the faces together. The

nature of the locking means may be said to be such that torsional stressis imposed on the clip.

The slight yielding of the stiff spring in the hinge results in animproved locking action,which is more secure and longer Wearing'than isthe case in those form's ofde'vice in which the resilience ofthe platesalone, or such resilience aided by undesirable looseness in the'hinge,is relied upon. With this invention, thepla'tes can be made'of stiiiermaterial and distortion of'the plates which'woul'd render'the deviceuseless need not occur, the strain being largely taken by a separatespring adapted 'to withstand it and to preserve its resilience. I

Another feature of the invention has to do with theknobs or fingerpieces 12 which protrude from the outer corners of the free eX-'tremiti'es oi the plates. The improvement in this respect consistsinskewing the finger pieces so that they are diagonal, both in the samesense, to the planes ofithe plates. The direction of the inclination issuch that,when effort is applied to the pieces 12-to open the clip,there is a resultant which "relievest-he pressure between the superposedsnap-engaging extremities, thereby making it easier to open the clip.

What is claimed as new is:

A clip and scalp protector forus'e in A connection withhair wavingappliances, comprising a pair of thincurved plates hinged together atone pair of superposed extremities and provided at their other"extremiies Wijai oma io n 3- i enLs t th it t s a engagn elemcooperative at a series of positions when'these extremities are pressedln'ward so as to pass one'o'ver the other, said elements comprising aprojection on the face of one of the plates "characterized in that thefirst-mentioned pair of extremitiesare hinged together by a headed "pin'wli iohprojects above theplates and that a stiff 'compression'spring isinterposed between thehead oi the pin andthe faceof one ersaideiitreniitiesfthe action of said'sp'ring beingperpendicularto'theplates.
